TRAVELING-CRANE STRUCTURE.

Application filed J'uly 17.191s.' Serial no. 245.321.

To all whom it may concern:

Be it known that we, FRANK BARTHOLO- MEW and NATHAN B. PAYNE, both citizens of the United States, and residing at New York city, in the county and State of New York, have made a certain new and useful Invention in Traveling-Crane Structures, of which the following is a specification.

This invention relates to traveling crane structures. V

The object of the invention is to provide means for attaching an auxiliary hoist device which is self-contained within itself to a main traveling crane structure, which latter is also self-contained Within itself.

A further object of the invention is to provide an auxiliary hoist device for traveling cranes so positioned and supported as to require no extra bridge or overhead space, but which will permit a complete traverse of the main crane from one limit to the other of its trackage without interference.

A further object of the invention is to provide an auxiliary hoist device or attachment which can be readily and easily applied toand without expensive change in the existing main traveling crane structures.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location, and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings, and finally pointed out in the appended claims.

Referring to the accompanying drawings and to the various views and reference signs appearing thereon- Figure 1 is a view in elevation of a main travehng crane structure showing an auxiliary hoist applied thereto in accordance with the principles of our invention, the tracks and supporting columns for the main crane structure being shown in verticaltransverse section.

The same part is designated by the samereference numeral wherever throughout the several views.

In the usual structures of traveling cranes it is a common practice to mount the nondriven wheels which carry the crane structure and which operate on the tracks upon stub axles fitted into a convenient part of the traveling structure. It is also the present common practice where auxiliary hoist devices are employed in connection with the it occurs main traveling crane structure to construct the auxiliary hoist as an integral part of the main trolley structure of thetraveling crane. This is expensive and introduces complications of structure by reason of the location of the integral auxiliary hoist installation. Sometimes the auxiliary hoist device is supported or carried by brackets cast ontothe main trolley of the'crane. This structure is objectionable for the reason that it involves an extension of the main trolley frame which prevents the main trolley from traversing the full length of its tracks thereby prescribing the range of travel of the main trolley, besides otherwise interfering with the available head room space. It has also been proposed to employ what is called in the art a wheelbarrow auxiliary hoist in connection with a main crane structure whereina frame projects beyond the main frame of the trolley upon which the auxilhoist is carried, the auxiliary frame being carried by wheels which operate upon the main crane tracks beyond the supporting Patented Got. 29, iaie.

.4, looking in the direction of the ar- I tional equipment required, and .further be-- cause of the bridge space occupied by the auxiliary attachment which limits and prescribes the extent of traverse of the main trolley along its supporting tracks.

We propose in accordance with the principles of our invention to avoid the objec tions above noted; and others, by eliminat ng the usual stub axles upon which the nondriven wheels of the main trolley are mounted and to substitute therefor a single axle to extend transversely across the main crane structure and upon the respective ends of which the non-driven wheels are carried, and to utilize this single axle as a means for supporting the auxiliary'hoist device or attachment.

Various means for attaching the auxiliary hoist device from the axle of the non-driven wheels may be employed, and we have shown various methods which are simple, practical and effective.

, Referring to the structure shown in Figs. 1, 2 and 3, 10 designates a portion of the main crane trolley, 11 the non-driven supporting wheels therefor, 12 the tracks upon which said wheels operate, and 13 the supporting bridge girders, or other means for supporting or carrying the tracks 12. These are parts of the ordinary self-contained traveling crane structure at present in common use, and in the particular structure thereof form no part of our present invention. Instead, however, of the non-driven wheels 11 each being carried on a suitable axle mounted in the main crane 10, as has been the common practice heretofore, we

' propose to employ in accordance with our invention a single axle or shaft 14 which extends between the wheels 11 and upon the ends of which said wheels are carried, and we also propose in accordance with our invention to utilize this transverse shaft 14 for supporting the auxiliary hoist device 15.

The latter may be of the usual or any well known unit structure complete and selfcontained within itself such as is marketed at present, and the specific details of structure of which forms no partof our present invention. In the form shown, in Figs. 1, 2 and 3, collars 16 are mounted upon the shaft 14 adjacent the bearings of said shaft in the main crane frame 10, and these collars are suitably bolted or otherwise secured as indicated at 17 to the ends of a bar 18 thereby suspending the bar 18 from its ends. If desired, bushings IQ -carried by the shaft 14 may receive the collars 16. The collars 16 and the depending portions thereof which are connected to the bar 18 constitute hangers for said bar. A suspending yoke 20 is carried by a pin 21 which extends transversely through the web of the bar 18, and, if desired, said web may be reinforced and strengthened at the point where the pin 21 passes therethrough by means of reinforcement plates 22 applied to the web of the bar 18. In this particular form of our device the bar 18 may be a section of I-beam. The auxiliary hoist unit 15 is detachably suspended from the yoke 20 by means of a hook.

23 carried by or connected to the'casing of auxiliary hoist unit 15 and engaging in the yoke 20. If desired, and in order to prevent lateral swing, displacement or rocking movement of the unit 15 upon its hook or suspension suitable straps 24 engage over the suspension beam 18 and are secured to the casing of the auxiliary hoist unit 15 said straps being disposed on .respectively opposite sides of the hook and yoke suspension as clearly shown in the drawings.

In the form shown in Figs. 4 and 5 a hollow sleeve 25 is telescoped over the =shaft'or axle 14 and is supported at its ends upon a bushing 26 which bears through a suitable antifriction bearing or lining 27 upon the shaft 14 closely adjacent the bearing thereof in the main crane framework 10. Supporting straps 28 passover the sleeve 25 and the ends thereof are bolted as at 29 to ears 30 cast or otherwise formed or provided on the casing of the hoist unit 15. In this arrangement it is preferable to employ suitable wedge blocks 31 held in place within the straps 28 by means of set screws 32 and positioned to engage the sleeve 25 at different points on the lower side thereof to steady the suspended auxiliary hoist and prevent lateral swinging movement thereof. It will be observed that in this form of our-invention as also is the case in the form shown in Figs. 1, 2 and 3, the weight of the suspended auxiliary hoist device is imposed upon the shaft or axle 14 near the ends thereof and adjacent the bearings of said shaft ends in the main crane framework. Consequently the danger is avoided of im osing undue bending strains upon the sha t or axle 14. In the form shown in Figs. 4 and 5 the sleeve 25 which directly carries the weight of the suspended auxiliary hoist forms in effect a journal hearing which the auxiliary shaft or axle 14 rotates, said sleeve 25 remaining stationary. Consequently the suspending straps 28 are relieved of the friction of rotation of the axle shaft 14 and therefore are not required to be bushed, the bushing of the bearing of sleeve 25 on shaft 14 being sufficient.

A somewhat modified and more. simple form of suspension is shown in Figs. 6 and 7 wherein a strap 34 engages over the sleeve 25 and is held against a displacement in a direction longitudinally of said sleeve in any suitable manner, as for example, by means of collars 36. The strap 34 has a de- In Figs. 8 and 9 is shown a somewhat modified arrangement of structure shown in Fig. 1 wherein 'a strap 38 engages over the suspension-bar or beam 18 and the hook 23 of the casing of auxiliary hoist unit engages in a depending portion '39 of said strap. The forms shown in Figs. 6, 7, 8

and 9 are e'fiective and simple as well as' economical, and are particularly well adapted for use in connection with compara tively light auxiliary hoist devices 15. In the .form shown in Figs. 8 and 9 the suspension strap 38 is held in place upon the beam 18 by means of a set screw 2 Whereas in thestructure shown in Fig. l the steadying straps 24 are employed it will be observed that the suspending straps 28 in the form shown in Fig. 4 perform the double function of suspension straps and also of steadying or bracing straps for the auxiliary hoist device. In the forms shown in Figs.

6, 7, 8 and 9 additional steadying or bracing straps such-as indicated at 24 in Fig. 1 may or may not be employed.

A structure of auxiliary hoist suspenslon employed in connection withour invention is well adapted for use generally includlng the operation of clam shell,orange peel, and similar buckets and their operation where a tripping line is employed to open and close the buckets in addition to the hoisting connection. would be operated for example, by the auxiliary hoist device 15 while the trlpping line would be operated in any suitable or convenient manner from the main crane frame, or vlce versa.

It is to be understood, of course, that the main crane is equipped with the usual cab for the operator from which the crane traversing motor is controlled, and it will likewise be understood that the auxiliary hoist device 15 which is ordinarily an electrically driven or operated device is 1n similar manner controlled from the main crane control cage.

The structure of auxiliary crane such as above described is not only simple and economical to construct, install or erect, but is efficient, can be readily applied at small expense to any existing traveling crane of the usual type and ,does not interfere in any manner with the operation of the main crane nor limit nor prescribe the length of its traverse along its supporting tracks nor does it interfere with the overhead space or working operations of the main crane.

While we have shown and described various forms of embodiment of our invention,

it is to be understood, of course, that the.

principles of our invention are equally applicable to other forms of structures. We
